Abstract:

A fully self consistent one dimensional ion beam slab interaction model has been applied to the investigation of the interaction of an energetic proton beam with an iron slab target. This model describes the slowing down of the beam, the hydrodynamic response and ionization dynamics of the slab, and detailed radiation emission and transport. An extensive atomic level structure with collisional radiative ionization dynamics is employed. A hybrid radiation transport algorithm consisting of a multifrequency formalism for the continuum and a probabilistic treatment of lines is used. The evolution of the Fe plasma with time is described. Calculated spectral emissions from the front and rear surfaces are presented at various times in the interaction.
